# Swap

Inter-token exchange must have a liquidity pool for that token pair, and the reserve value for token token\_address\_in must be at least amount. 

If all conditions are met and the contract is performed, the number of tokens in token\_in\_address from the user's wallet will be transferred to the liquidity pool by amount\_in, and tokens for token\_address\_out will be paid. 

Setting minimum\_amount\_out prevents swaps when set below the corresponding quantity.
